FIELD OF THE INVENTION

The present invention relates to heteroaryl heterocyclic compounds,pharmaceutical compositions comprising same, methods for preparing same,and uses thereof.

BACKGROUND OF THE INVENTION

Bruton's Tyrosine kinase (BTK), a member of non-receptor tyrosineprotein Tec family (including BTK, LTK, TEC, BMX, TXK and the like), iswidely expressed in hematopoietic cells except for T cells, NK cells anddifferentiated plasma cells. BTK plays an important role in signalingmediated by B cell antigen receptor (BCR) and Fcγ receptor (FcγR) in Bcells and myeloid cells, respectively. It is a key regulator on the Bcell development, activation, signaling and survival. BTK can controlthe development and differentiation of B cells by activating positiveregulatory factors and differentiation factors of cell cycle, and canalso control the survival and proliferation of B cells by regulating theexpressions of pro-apoptotic proteins and anti-apoptotic proteins. BTKalso plays an important role in the migration and adhesion of B lymphomacells. In addition, BTK plays a role in many other hematopoieticsignaling pathways, such as Toll-like receptor (TLR) and cytokinereceptor-mediated TNF-α production in macrophages, signaling mediated byIgE receptor (FceRI) in mast cells, inhibition of Fas/APO-1 inducedapoptotic signal in B-type lymphoid cells, and collagen induced plateletaggregation.

In humans, BTK gene mutation would lead to a hereditary immunodeficiencydisease, X-linked agammaglobulinaemia (XLA). Point mutation of BTK geneis implicated in human XLA patients, associated with low to undetectiveBTK mRNA level and BTK protein expression, as a consequence, almostcompletely lack of the maturation and the development of B cells andimmunoglobulins, and significant attenuation of persistent calciumsignal in response to BCR stimulation. The effect of BTK mutation isonly restricted on B cell populations, no significant developmentdefects in other immune cells found in XLA patients. Spontaneousmutations of BTK gene were also found in X-linked immunodeficiency (xid)mice, showing a similar but less severe phenotype. In xid mice ormutation induced BTK gene knock-out mice, B cell differentiation waspartially blocked at the B cell stage, with reduced number of mature Bcells in blood circulation, and resistance to models of collagen-inducedarthritis and staphylococcus-induced arthritis. It has been indicated bya large amount of evidences that BTK is abundantly expressed in thecirculating B cells in the patients with autoimmune diseases such asrheumatoid arthritis (RA), primary Sjogren's syndrome (pSS) and systemiclupus erythematosus (SLE), as well as B-cell leukemia and lymphoma. Theaberrant activation of BCR signaling has been confirmed in theseautoimmune diseases and B cell related diseases. Inhibition of B cells,BCR signaling pathway and BTK may slow down the progression of thediseases to varying degrees.

Based on the key role of BTK in the development and functions of Bcells, BTK is considered as a potential target for the treatment of Bcell malignancies and autoimmune diseases. A variety of BTK inhibitorsare being developed for the clinical research of hematologicmalignancies and autoimmune diseases. Small molecule BTK inhibitors(such as ibrutinib, acalabrutinib, zanubrutinib, PRN1008, GDC-0853) haveshown promising therapeutic efficacies. For example, ibrutinib, anirreversible BTK inhibitor, with a relatively high durable efficacy andlow toxicity in clinical studies, has been approved by U.S. Food andDrug Administration (FDA) for the treatment of relapsed mantle celllymphoma (MCL) in 2013, chronic lymphocytic leukemia (CLL) in 2014,Waldenstram's macroglobulinaemia (WM) in 2015, and relapsed/refractorymarginal zone lymphoma (MZL) in 2017. In particular, the approvedindications were extended to chronic graft-versus-host disease (GVHD) in2017, demonstrating the mechanism of BTK in the treatment of chronicautoimmune diseases. In addition, the irreversible BTK inhibitoracalabrutinib was approved for the treatment of adult MCL in 2017 andfor CLL in 2019; zanubrutinib was approved by FDA for the treatment ofMCL in November 2019; and a phase 3 study of PRN1008 against pemphigusis ongoing. Some irreversible BTK inhibitors (tirabrutinib, spebrutinib,and evobrutinib) and reversible BTK inhibitors (GDC-0853, ARQ-531 andLOXO-305) have been on the stage of pre-clinical and clinicaldevelopment.

Therefore, BTK inhibitors represent attractive therapy for the treatmentof related diseases, especially cancer, inflammatory diseases orautoimmune diseases.

Any asymmetric atom (e.g. carbon, etc.) of a compound of formula (I) mayexist in an racemic or enantiomeric rich form, for example in (R)-, (S)-or (RS)-configuration. In some embodiments, asymmetric atoms have atleast 50%, at least 60%, at least 70%, at least 80%, at least 90%, atleast 95%, at least 99%, or 100% enantiomeric excess in (R)- or (S)configurations, respectively.

When a structural formula or chemical name herein contains “(RS)”, itmeans any mixture of (R) configuration and (S) configuration of thecompound.

The term “optional” or “optionally” as used herein means that thesubsequently described event or circumstance may or may not occur, andthe description includes instances wherein the event or circumstanceoccur and instances in which it does not occur. For example, “optionallysubstituted with one or more” includes unsubstituted and substitutedwith 1, 2, 3 or more substituents as described. It will be understood bythose skilled in the art, with respect to any group containing one ormore substituents, that such groups are not intended to introduce anysubstitution or substitution patterns that are sterically impractical,chemically incorrect, synthetically non-feasible and/or inherentlyunstable.

The term “substituted” or “substituted with . . . ”, as used herein,means that one or more (such as, 1, 2, 3 or 4) hydrogens on thedesignated atom or group are replaced with one or more (such as 1, 2, 3or 4) substituents, preferably the substituents chosen from theindicated group of substituents or radicals, provided that thedesignated atom's normal valence is not exceeded. The said substituentsmay be the same or different from each other. The term “substituted withone or more groups chosen from” or “substituted with one or more” asused herein means that one or more hydrogens on the designated atom orgroup are independently replaced with one or more radicals from theindicated group of substituents or radicals, wherein the said radicalsmay be the same or different from each other. Preferably, “substitutedwith one or more groups chosen from” or “substituted with one or more”means that the designated atom or group is substituted with 1, 2, 3, or4 radicals independently chosen from the indicated group of substituentsor radicals, wherein the said radicals may be the same or different fromeach other. In some embodiments, when a substituent is oxo (i.e., ═O),then 2 hydrogens on a single atom are replaced by the oxo. An optionalsubstituent can be any radicals, provided that combinations ofsubstituents and/or variables result in a chemically correct and stablecompound. A chemically correct and stable compound is meant to imply acompound that is sufficiently robust to survive sufficient isolationfrom a reaction mixture to be able to identify the chemical structure ofthe compound. Preferably, substituents are those exemplified in thecompounds of the embodiment of the present application.

Unless otherwise specified, substituents are named into the corestructure. For example, it is to be understood that when(cycloalkyl)alkyl is listed as a possible substituent, the point ofattachment of this substituent to the core structure is in the alkylportion.

It will be appreciated by the person of ordinary skill in the art(“POSITA”) that some of the compounds of formula (I) may contain one ormore chiral centers and therefore exist in two or more stereoisomericforms. The racemates of these isomers, the individual isomers andmixtures enriched in one enantiomer, as well as diastereomers when thereare two chiral centers, and mixtures partially enriched with specificdiastereomers are within the scope of the present invention. It will befurther appreciated by the POSITA that the present invention includesall the individual stereoisomers (e.g. enantiomers), racemic mixtures orpartially resolved mixtures of the compounds of formula (I) and, whereappropriate, the individual tautomeric forms thereof.

The racemates can be used as such or can be resolved into theirindividual isomers. The resolution can afford stereochemically purecompounds or mixtures enriched in one or more isomers. Methods forseparation of isomers are well known (cf. Allinger N. L. and Eliel E. L.in “Topics in Stereochemistry”, Vol. 6, Wiley Interscience, 1971) andinclude physical methods such as chromatography using a chiraladsorbent. Individual isomers can be prepared in chiral form from chiralprecursors. Alternatively, individual isomers can be separatedchemically from a mixture by: forming diastereomeric salts with a chiralacid (such as the individual enantiomers of 10-camphorsulfonic acid,camphoric acid, alpha-bromocamphoric acid, tartaric acid,diacetyltartaric acid, malic acid, pyrrolidone-5-carboxylic acid, andthe like), fractionally crystallizing the salts, and then freeing one orboth of the resolved bases, optionally repeating the process, so asobtain either or both substantially free of the other; i.e., in a formhaving an optical purity of >95%. Alternatively, the racemates can becovalently linked to a chiral compound (auxiliary) to producediastereomers which can be separated by chromatography or by fractionalcrystallization after which time the chiral auxiliary is chemicallyremoved to afford the pure enantiomers, as is known to the POSITA.

The term “tautomer” as used herein refers to constitutional isomers ofcompounds generated by rapid movement of an atom in two positions in amolecule. Tautomers readily interconvert into each other, e.g., enolform and ketone form are tipical tautomers.

A “pharmaceutically acceptable salt” is intended to mean a salt of afree acid or base of a compound of Formula (I) that is non-toxic,biologically tolerable, or otherwise biologically suitable foradministration to the subject. For example, an acid addition saltincludes such as a salt derived from an inorganic acid and an organicacid. Said inorganic acid includes such as hydrochloric acid,hydrobromic acid, hydroiodic acid, sulfuric acid, phosphoric acid, andnitric acid; said organic acid includes such as p-toluenesulfonic acid,salicylic acid, methanesulfonic acid, oxalic acid, succinic acid, citricacid, malic acid, lactic acid, fumaric acid, and the like. For examples,see, generally, S. M. Berge, et al., “Pharmaceutical Salts”, J. Pharm.Sci., 1977, 66:1-19, and Handbook of Pharmaceutical Salts, Properties,Selection, and Use, Stahl and Wermuth, Eds., Wiley-VCH and VHCA, Zurich,2002.

In addition, if a compound of the present invention herein is obtainedas an acid addition salt, the free base can be obtained by basifying asolution of the acid addition salt. Conversely, if the product is a freebase, an acid addition salt, particularly a pharmaceutically acceptableacid addition salt, may be produced by dissolving the free base in asuitable solvent and treating the solution with an acid, in accordancewith conventional procedures for preparing acid addition salts from basecompounds. The POSITA will recognize various synthetic methodologiesthat may be used without undue experimentation to prepare non-toxicpharmaceutically acceptable acid addition salts or base addition salts.

The term “deuterated compound” or “deuterates” refers to a compound inwhich one or more hydrogen atoms, such as 1, 2, 3, 4 or 5 hydrogenatoms, are replaced by deuterium atoms (D).

The term “solvates” means solvent addition forms that contain eitherstoichiometric or non-stoichiometric amounts of solvent. Some compoundshave a tendency to trap a fixed molar ratio of solvent molecules in thesolid state, thus forming a solvate. If the solvent is water, thesolvate formed is a hydrate, when the solvent is alcohol, the solvateformed is an alcoholate. Hydrates are formed by the combination of oneor more molecules of water, or less than one molecule of water, with onemolecule of the substances in which the water retains its molecularstate as H₂O, such combination being able to form one or more hydrates,for example, hemihydrate, monohydrate, and dihydrate.

As used herein, the terms “group(s)” and “radical(s)” are synonymous andare intended to indicate functional groups or fragments of moleculesattachable to other fragments of molecules.

The term “active ingredient” is used to indicate a chemical substancewhich has biological activity. In some embodiments, an “activeingredient” is a chemical substance having pharmaceutical utility.

The term “pharmaceutical combination” as used herein means a productobtained by mixing or combining two or more active ingredients,including fixed and non-fixed combinations of active ingredients, suchas a kit, and a pharmaceutical composition. The term “fixed combination”means that two or more active ingredients (such as compounds of thepresent invention and additional therapeutic agents) are administeredsimultaneously to a patient in the form of a single entity or dose. Theterm “non-fixed combination” means that two or more active ingredients(such as compounds of the present invention and additional therapeuticagents) are administered simultaneously, in parallel or successively toa patient in separate entities, wherein the administration provides thepatient with a therapeutically effective level of the compound.

The terms “treating” or “treatment” or “prevention” of a disease ordisorder, in the context of achieving therapeutic benefit, refer toadministering one or more pharmaceutical substances, especially acompound of formula (I) described herein to a subject that has thedisease or disorder, or has a symptom of a disease or disorder, or has apredisposition toward a disease or disorder, with the purpose to cure,heal, alleviate, relieve, alter, remedy, ameliorate, improve, or affectthe disease or disorder, the symptoms of the disease or disorder, or thepredisposition toward the disease or disorder. In some embodiments, thedisease or disorder is cancer, such as solid tumors or hematologicmalignancies, including lymphoma, leukemia and myeloma. In anotherembodiment, the disease or disorder is an inflammatory diseases orautoimmune disease.

The terms “treating”, “contacting” and “reacting,” in the context of achemical reaction, mean adding or mixing two or more reagents underappropriate conditions to produce the indicated and/or the desiredproduct. It should be appreciated that the reaction which produces theindicated and/or the desired product may not necessarily result directlyfrom the combination of two reagents which were initially added, i.e.,there may be one or more intermediates which are produced in the mixturewhich ultimately lead to the formation of the indicated and/or thedesired product.

The term “effective amount” as used herein refers to an amount or doseof an BTK inhibiting agent sufficient to generally bring about atherapeutic benefit in patients in need of treatment for a disease ordisorder mediated by BTK or at least in part by BTK. Effective amountsor doses of the active ingredient of the present disclosure may beascertained by methods such as modeling, dose escalation studies orclinical trials, and by taking into consideration factors, e.g., themode or route of administration or drug delivery, the pharmacokineticsof the agent, the severity and course of the disease or disorder, thesubject's previous or ongoing therapy, the subject's health status andresponse to drugs, and the judgment of the attending physician.

An exemplary dose is in the range of from about 0.0001 to about 200 mgof active agent per kg of subject's body weight per day, such as fromabout 0.001 to 100 mg/kg/day, or about 0.01 to 35 mg/kg/day, or about0.1 to 10 mg/kg daily in single or divided dosage units (e.g., BID, TID,QID). For a 70-kg human, an illustrative range for a suitable dosageamount is from about 0.05 to about 7 g/day, or about 0.2 to about 5g/day. Once improvement of the patient's disease or disorder hasoccurred, the dose may be adjusted for maintenance treatment. Forexample, the dosage or the frequency of administration, or both, may bereduced as a function of the symptoms, to a level at which the desiredtherapeutic effect is maintained. Of course, if symptoms have beenalleviated to an appropriate level, treatment may cease. Patients may,however, require intermittent treatment on a long-term basis upon anyrecurrence of symptoms.

The term “inhibition” or “inhibiting” indicates a decrease in thebaseline activity of a biological activity or process. The term“inhibition of BTK activity” is a practical pharmaceutical activity forpurposes of this disclosure and refers to a decrease in the activity ofBTK as a direct or indirect response to the presence of the compound ofthe present invention, relative to the activity of BTK in the absence ofthe compound of the present invention. The decrease in activity may bedue to the direct interaction of the compound of the present inventionwith BTK, or due to the interaction of the compound of the presentinvention, with one or more other factors that in turn affect the BTKactivity. For example, the presence of the compound of the presentinvention may decrease the BTK activity by directly binding to the BTK,by causing (directly or indirectly) another factor to decrease the BTKactivity, or by (directly or indirectly) decreasing the amount of BTKpresent in the cell or organism.

The term “subject” or “patient” as used herein means mammals andnon-mammals. Mammals means any member of the mammalia class including,but not limited to, humans; non-human primates such as chimpanzees andother apes and monkey species; farm animals such as cattle, horses,sheep, goats, and swine; domestic animals such as rabbits, dogs, andcats; laboratory animals including rodents, such as rats, mice, andguinea pigs; and the like. Examples of non-mammals include, but are notlimited to, birds, and the like. The term “subject” or “patient” doesnot denote a particular age or sex. In some embodiments, the subject orpatient is a human.

In general, the term “about” is used herein to modify a numerical valueabove or below the stated value by a variance of 20%.

Technical and scientific terms used herein and not specifically definedhave the meaning commonly understood by the POSITA to which the presentdisclosure pertains.

All numerical ranges herein shall be interpreted as disclosing eachnumerical value and subset of numerical values within the range,regardless of whether they are specifically otherwise disclosed. Forexample, when referring to any range of values, it should be regarded asreferring to every value within the range of values, for example, everyinteger within the range of values.

2. Methods

Z′-LYTE® biochemical assay employs a fluorescence resonance energytransfer (FRET)-based, coupled-enzyme format and is based on thedifferential sensitivity of phosphorylated and non-phosphorylatedpeptides to proteolytic cleavage. Both ends of the short peptidesubstrate are labeled with two fluorescent groups to form a FRET pairedcombination. In the primary reaction (the Kinase Reaction), the kinasetransfers the γ-phosphate of ATP to a single serine or threonine residueon the short peptide substrate. In the secondary reaction (thedevelopment reaction), the non-phosphorylated short peptides wererecognized and cleaved by a site-specific protease (the developmentreagent). Phosphorylated short peptides can resist such cleavage.Cleavage of short peptides can disrupt the donor (such as coumarin) andreceptor fluorophores (fluorescein) on the short peptides, while thephosphorylated short peptides can maintain FRET. The calculation methodof the ratio is as follows, and the ratio of the respective emissionsignals generated by the donor fluorophores emitted (after excitation at400 nm) to the receptors is calculated. Emission signal ratio=emittedlight by coumarin (445 nm)/emitted light by fluorescein (520 nm). If theFRET short peptide is phosphorylated (such as no kinase inhibitor), theemitted light ratio will remain in a lower level. If the FRET shortpeptide is non-phosphorylated (such as kinase inhibitor), the emittedlight ratio will be in a higher level. In this way, the inhibitoryeffects of different compound inhibitors on BTK kinase activity would bedistinguished.

The experiment were carried out according to the instructions of theZ′-LYTE® kinase test kit-tyrosine 1 peptide. Reagent preparation: 1.33×kinase buffer: 5× kinase buffer was diluted with water to 1.33× kinasebuffer; an enzyme solution: the kinase was dissolved in 1.33× kinasebuffer with the final working concentration being 3.32 nM; a shortpeptide solution: a short peptide stock solution (1 mM dissolved inDMSO) was dissolved in 1.33× kinase buffer with the final workingconcentration being 2 μM; Z′-LYTE Tyr01 phosphorylated short peptidesolution, 0.6 μl of stock solution (1 mM dissolved in DMSO) wasdissolved in 149.4 μl of 1.33× kinase buffer; an ATP solution: an ATPstock solution (10 mM aqueous solution) was dissolved in 1.33× kinasebuffer with the final working concentration being 32 μM; acolor-developing solution: color-developing solution B was dissolved incolor-developing buffer with the final working concentration being 1×color-developing solution; 4× compound preparation: the compound wasdiluted in 3-fold gradient concentration to finally obtain 4% DMSOaqueous solution containing different concentrations of the compound,with the final working concentration being 3000, 1000, 333.33, 111.11,37.04, 12.35, 4.12, 1.37 nM, 8 concentration points in total.

Specific steps of the experiment: In the experiment, there were threecontrol groups, each with 8 replicate wells, which were C1 100%inhibition group (no ATP), C2 0% inhibition group (with ATP), and C3100% phosphorylation group, respectively. 2.5 μl of serially dilutedcompound was added to each well of a 384-well plate, with doublereplicate wells, and 4% DMSO solution was added to wells C1, C2, and C3.After that, except for wells C3, 2.5 μl of BTK enzyme solution was addedto each remaining well, which was left to stand at 4° C. for 30 minutes.After that, except for wells C3, 2.5 μl of short peptide solution wasadded to each well, and 5 μl of phosphorylated short peptide solutionwas added to each of wells C3. 2.5 μl of 1.33× kinase buffer was addedto each of wells C1 and C3, and 2.5 μl of ATP solution was added to eachof the remaining wells. The wells were centrifuged transiently, and theplate was shaken at 1000 rpm for 30 seconds to perform transientcentrifuge. The 384-well plate was placed in a shaking incubatorprotected from light and incubated at room temperature for 1 hour. Afterthe enzymatic reaction was completed, 5 μl of development solution wasadded to each well, which was centrifuged transiently, and the plate wasshaken at 1000 rpm for 30 seconds to perform transient centrifuge. The384-well plate was placed in a shaking incubator protected from lightand incubated at room temperature for 1 hour until the color-developingreaction was completed.

3. Detection

After the development reaction was completed, the 384-well plate wastaken out to perform plate reading using the Envision multi-mode platereader, and the optical signal was detected at the emission wavelengthof 405 nm and the excitation wavelength of 460 nm/535 nm. The readingvalue at 460 nm/535 nm of each well was used as the signal value of eachwell.

4. Calculation

The average signal value of C3 was regarded as 100% phosphorylation, theaverage signal value of C1 was regarded as 0% phosphorylation, and theaverage signal value of C2 was used to calculate the phosphorylationratio of short peptides in the presence of BTK kinase. According to thesignal value in each well, the inhibition ratio (%) of eachconcentration of compounds was calculated, and the 205 model in XL-Fit5.3 software (ID Business Solutions Limited) was used to obtain an IC₅₀value.

The phosphorylation ratio is calculated as follows:

Phosphorylation ratio (%)=100−100×[(emission signal ratio×F _(100%))−C_(100%)]/{(C _(0%) −C _(100%))+[emission signal ratio×(F _(100%) −F_(0%))]}

wherein, the emission signal ratio=coumarin emission signal (460nm)/fluorescein emission signal (535 nm); C_(100%)=average value ofcoumarin emission signal in C3; C_(0%)=average value of coumarinemission signal in C1; F_(100%)=average value of fluorescein emissionsignal in C3; F_(0%)=average value of fluorescein emission signal in C1.

The inhibition ratio is calculated as follows:

Afterculturing for 1 hour, the test compound was diluted with Hank's balancedsalt solution in 4-fold gradient to the corresponding concentrations,and then 5 μL/well of the diluted test compound with differentconcentrations (the final concentrations of the test compound were 3.0,0.75, 0.188, 0.047, 0.012, 0.0029, 0.0007 and 0.00018 μM, and the finalconcentration of DMSO was 0.3%, double replicate wells) or 5 μL/well ofcontrol solution (1.5% DMSO, 8 replicate wells) were added to 20 μL/wellof cell culture system, which incubated together for another hour, then5 μL/well of a mixed solution of human immunoglobulin M (finalconcentration was 10 μg/mL) and hydrogen peroxide (final concentrationwas 3.3 mM) diluted with Hank's balanced salt solution was added to thetreating wells for the test compound and the control treating wells foranti-human immunoglobulin M, and 5 μL/well of Hank's balanced saltsolution was added to negative control treating wells. The plate wasincubated in a 5% CO₂, 37° C. cell incubator for 10 minutes.

10 μL/well of cell lysis buffer was added to each well of a 96-wellplate, which was mixed well and lysed at room temperature for 30minutes. 16 μL/well of lysis buffer was pipetted to a new 384 wellplate, and then added 4 μL/well of phosphorylated BTK antibody,centrifuged (1000 rpm) for 1 minute, then shaken for 1 minute, furthercentrifuged (1000 rpm) for 1 minute, and finally placed in a constanttemperature incubator overnight. Detection was performed on the nextday.

3. Detection

The 384 well plate incubated overnight in the constant temperatureincubator was taken out to detect the luminescence signal using theEnvision microwell plate reader at the emission wavelength of 320 nm andexcitation wavelength of 665 nm/615 nm. The reading value at 665 nm/615nm of each well multiplied by 104 was used as the signal value of eachwell.

4. Calculation

The average signal value of the wells supplemented with the mixedsolution of human immunoglobulin M (final concentration was 10 μg/mL)and hydrogen peroxide (final concentration was 3.3 mM) without the testcompound was regarded as the high value, and the average signal value ofthe wells without immunoglobulin M stimulation and without the testcompound was regarded as the low value. According to the signal value ineach well, the inhibition ratio (%) of each concentration of compoundswas calculated, and the 205 model in XL-Fit 5.3 software (ID BusinessSolutions Limited) was used to obtain an IC₅₀ value.

The inhibition ratio is calculated as follows:

inhibition ratio (%)=100%−{(treating well for the test compound−negativecontrol treating well)/(control treating well for anti-humanimmunoglobulin M−negative control treating well)}×100%, wherein,

Treating well for the test compound: represents the signal value ofRamos cells treated with anti-human immunoglobulin M, hydrogen peroxideand the test compound.

Control treating well for anti-human immunoglobulin M: represents thesignal value of Ramos cells treated with anti-human immunoglobulin M,hydrogen peroxide but without the test compound.

Negative control treating well: represents the signal value of Ramoscells without the test compound and without immunoglobulin stimulation.

Example 5 Stability Test in Liver Microsomes 1. Experiment Materials:

Both male CD-1 mouse pooled liver microsomes and male SD rat pooledliver microsomes were purchased from BioreclamationIVT Corporation, USA.

Phenacetin, glucose-6-phosphate dehydrogenase (G-6-PDH) and nicotinamideadenine dinucleotide phosphate (NADP) were all purchased fromSigma-Aldrich Corporation, USA. Glucose-6-phosphate (G-6-P) waspurchased from Shanghai Eybridge Chemical Technology Co., Ltd.

2. Solution Preparation:

Ten mM test compound stock solution: a certain amount of test compoundwas weighed, and dissolved with an appropriate volume of DMSO to preparea stock solution with a concentration of 10 mM for use.

Reaction stopping solution: an appropriate amount of internal standardcompound phenacetin was dissolved in acetonitrile to prepare a reactionstopping solution with a concentration of 1000 ng/mL for use at roomtemperature.

3. Experiment Method:

The test compound stock solution was diluted with an organic solvent(usually a mixture of acetonitrile, methanol and water with variousratios, depending on the solubility of the compound, if necessary, 1 Nhydrochloric acid or 1 N sodium hydroxide would be added to facilitatesolubilization) to the 0.1 mM (the final concentration of the compoundin the reaction system was 1 μM) and the concentration percentage of theorganic solvents in the incubation system no more than 1% (wherein thepercentage of DMSO was required to be no more than 0.1%). An appropriateamount of 100 mM NADP, 500 mM G-6-P and 100 Unit/mL G-6-PDH were mixedand diluted with ultrapure water (the final system contains 1 mM NADP, 5mM G-6-P and 1 Unit/mL G-6-PDH), pre-incubated in a 37° C. water bathfor 10 minutes and then placed on ice for use as a NADPH regenerationsolution. 20 mg/mL liver microsomes solution and 200 mM phosphate bufferwas mixed, and diluted with ultrapure water to give a liver microsomessolution containing 2.5 mg/mL liver microsomes (the final concentrationof the reaction system is 0.5 mg/mL) and 50 mM phosphate buffer. Thediluted liver microsomes solution was mixed with 0.1 mM compoundsolution, a mixture of 100 mM EDTA, 300 mM MgCl₂ solution, 200 mMphosphate buffer (the final system was 3 mM MgCl₂, 1 mM EDTA and 50 mMphosphate buffer) and water in an appropriate volume was added. Finally,the NADPH regeneration solution was added, then the reaction solutionwas placed in a 37° C. water bath to start the reaction (the reactiontime was 30 minutes), and the reaction was stopped by adding theice-cold acetonitrile reaction stopping solution containing the internalstandard. The 0-minute sample was not incubated in a 37° C. water bath,and its difference from the 30-minute sample further lies in that theice-cold acetonitrile reaction stopping solution containing the internalstandard was added first, and then the NADPH regeneration solution wasadded. The sample added with the reaction stopping internal standardsolution was vortexed and mixed well, and then centrifuged at 4400 rpmfor 10 minutes. The supernatant was taken and diluted ten times with 50%methanol for LC-MS/MS analysis.

4. Analysis Method:

LC-MS/MS was used to determine the concentration of the compound in thesample. The percentage of the remaining compound after 30 minutes ofincubation comparing with that in the 0-minute sample was calculatedusing the peak area ratio of the compound to the internal standard as anindicator, to evaluate the metabolic stability of the compound.

When theaverage tumor volume reached about 400 mm³, animals were randomlyassigned to the following groups with 8 animals per group according tothe tumor volume:vehicle control, positive reference compound Ibrutinib(Shanghai Tianxi Chemical Co., LTD) (50 mg/kg), reference compoundGDC-0853 (10 mg/kg), compound 19 (10 mg/kg and 30 mg/kg). Ibrutinib wasformulated in 0.5% sodium methylcellulose solution, and GDC-0853 andcompound 19 were prepared in 0.5% hydroxypropyl methylcellulose solution(pH=3). All drugs were administered by oral gavage, once a day, and thevehicle control group was administered orally with 0.5% hydroxypropylmethylcellulose solution (pH=3).

Tumor volumes (tumor volume=0.5× long diameter×short diameter²) and bodyweights of the mice were measured regularly. The tumor volume change andbody weight were statistically analyzed, with p<0.05 consideredstatistically significant, and p<0.01 as extremely statisticallysignificant.

The anti-tumor activity was evaluated by tumor growth inhibition.

Tumor growth inhibition (TGI%)=100%×(1−(TV_(Dt (treatment group))−TV_(D0 (treatment group)))/(TV_(Dt (control group))−TV_(D0 (control group))))

Relative body weight (RBW %)=BW_(Dt)/BW_(D0)×100%

wherein, TV_(D0) represents the tumor volume obtained at firstmeasurement, namely, the tumor volume before drug administration, andTV_(Dt) represents the tumor volume on the day of measurement; BW_(D0)represents the body weight of the animal obtained at first measurement,namely, the body weight of the animal before drug administration;BW_(Dt) represents the body weight of the animal on the day ofmeasurement.

Example 9 Therapeutic Effect of the Compound of the Present Invention ona Rat Arthritis Model Induced by Type II Collagen Study Methods

An appropriate amount of bovine type II collagen (CII, Chondrex(Redmond, Wash., USA), Cat #20021) was weighed and dissolved in 0.1 moleof acetic acid (SPGC Sinopharm Chemical Reagent Co., Ltd (Shanghai,P.R.China), Cat #: 10000218.), which was formulated into a solution witha concentration of 6 mg/mL, stirred at 4° C. overnight, and added withan equal volume of Freund's incomplete adjuvant (Sigma-Aldrich. (St.Louis, Mo., USA), Cat #: SLBW0366.), fully emulsified to prepare anemulsion with a CII concentration of 3 mg/mL.

Female Lewis rats were purchased from Beijing Vital River LaboratoryAnimal Technology Co., Ltd (certificate number 1100111911070522, initialbody weight of 110-130 grams), and 3 rats were randomly selected asnormal group, and the remaining rats were grouped according to thefollowing table. In the first immunization on day 0, the rats exceptthat in the normal group were anesthetized with isoflurane (Hebei YipinPharmaceutical Co., Ltd., Lot: C002170601.), and then disinfected with75% alcohol. 0.2 mL of emulsion was injected intradermally at the baseof the tail thereof. A second challenge was carried out on day 7, and0.2 mL of emulsion was intradermally injected using the same method.

After grouping and modeling, the normal group was not administered, andthe rats in the other groups were administered with the control vehicle,4 mg/kg of the reference GDC-0853, and each dose of compound 19 orallyonce a day until the end of the experiment. Grouping and dosage regimenare shown in Table 6.

The paw volume was measured on day 8 after immunization, and the leftand right hind paw volumes (V) were measured every day after the pawvolume increase was detected.

The arthrosis paw volumes of the left and right hind limbs of eachanimal were measured, and the average paw volume (APV, which shows theswelling change of the paw of the animal) was calculated according tothe following formula:

Average paw volume APV=(V _(left) +V _(right))/2

Effect of drugs on the average paw volume was subjected to significanceanalysis by GraphPad with repeated measure ANOVA and Dunnett's multiplecomparisons test, and the p value was calculated, wherein #P<0.01indicated that there was a significant difference compared with thenormal group, and **p<0.01 indicated that there was a significantdifference compared with the vehicle control group.

The average arthrosis paw volume of each animal before administrationwas used as the baseline (or considered 100% inhibition ofinflammation). The averaged paw swelling (APS) of each animal iscalculated according to the following formula, wherein, APV_(d1) is theaverage paw volume of the animal administered on day 1, and APV_(dt) isthe average paw volume of the animal administered on day t:

The averaged paw swelling APS_(dt)=(APV_(dt)−APV_(d1))

The area under the curve (AUC) of the average paw volume change is thearea under the curve of the arthrosis score change calculated by thetrapezoid method, and the calculation formula is:

AUC_(paw volume)=½×(APS_(d1)+APS_(d2))×(d ₂ −d₁)+½×(APS_(d2)+APS_(d3))×(d ₃ −d ₂)+ . . . +½×(APS_(dn)+APS_(d(n-1)))×(d_(n) −d _(n-1))

ED₅₀ is calculated by XLfit software according to the AUC inhibitionratio of the area under the curve of the average paw volume change. Theselected model is “log (inhibitor) vs. response—Variable slope”:

$y = {A + {\frac{B - A}{1 + \left( \frac{C}{x} \right)^{D}}.}}$

Results

Lewis rats started to develop symptoms on day 11 after the firstimmunization with bovine type II collagen, and the paw volume of theright hind limb gradually increased with the developing of course of thedisease. The paw volume increase of the rat in the vehicle control groupwas compared with that in the normal group, there was a statisticallysignificant difference (^(##)p<0.01). The paw volume of the rat withGDC-0853 was significantly reduced (**p<0.01) compared with that in thevehicle control group.
